Abstract (en)
Flow sensor device (1) comprising a housing (10) with a flow channel (11) following a central flow line (N) for a fluid flow. The device (1) comprises at least one flow sensor element (12) and at least one flow grid (2), wherein the flow sensor element (12) is accommodated in the housing (10). The flow grid (2) is arranged upstream of the flow sensor element (12) and extends from a grid center (21) on the central flow line (N) in a radial direction (R) substantially transversely to the central flow line (N). The flow grid (2) is a single-piece plate element with a plurality of openings (22), wherein opening diameters (220) of the openings (22) range from 50 micrometers to 1 millimeter. Moreover, the present invention relates to such a flow grid (2) and to a method of production thereof.
